Abstract

Un método que utiliza técnicas de interpolacion estadística para analizar y simular la variabilidad y continuidad espaciales de datos sobre frecuencias deradio que se hubo recogido de un sistema celular de radio. Al método se lo utiliza para el plane amiento y el manejo de sistemas celulares. Después de lainstalacion y de la preparacion de estaciones de base celulares, se pone en práctica ulteriores análisis y refinamiento de los datos de RF, para determinar lacobertura de senal de la torre, la u bicacion de huecos de RF en el sistema, la reutilizacion de frecuencias y la superposicion de senales de RF entre dostorres, o más, que producen interferencia. El método analiza datos en crudo sobre potencia de RF, que se recogen por medio de la real izacion de ensayos dedesplazamiento de una muestra de caminos en un sistema celular. A través de krigado se determina un modelo geoestadístico de la propagacion de Rf en un sistemacelular. La estimacion de la tendencia de la pérdida de trayectoria de RF se extrae de cada uno de los datos en crudo y de ella se elabora un modelo paradescribir la variabilidad de los datos de un extremo al otro de toda la zona del sistema celular. Entonces se prepara un mapa de senales para la pérdidaestimada de pro pagacion, para cualquier zona de interés dentro de un sistema celular.A method that uses statistical interpolation techniques to analyze and simulate the spatial variability and continuity of radio frequency data that had been collected from a cellular radio system. The method is used for planning and management of cellular systems. After the installation and preparation of cellular base stations, further analysis and refinement of the RF data is carried out, to determine the signal coverage of the tower, the location of RF holes in the system, the reuse of frequencies and overlapping RF signals between dostors, or more, that produce interference. The method analyzes raw data on RF power, which are collected through the realization of displacement tests of a sample of roads in a cellular system. Through krigado a geostatistical model of the propagation of Rf in a cellular system is determined. The estimation of the trend of the loss of RF trajectory is extracted from each of the raw data and from it a model is developed to describe the variability of the data from one end to the other of the entire area of the cellular system. A signal map is then prepared for the estimated loss of pro pay, for any area of interest within a cellular system.
